Understanding patient perceptions following a psycho-educational intervention for psychogenic non-epileptic seizures

Stigma in functional neurological disorder (FND) - A systematic review

OBJECTIVE

The purpose of this systematic review was to evaluate stigma and Functional Neurological Disorder (FND) regarding: 1) prevalence and associated factors, 2) the nature and context of stigma in FND, and 3) stigma-reduction interventions.

METHODS

We searched four relevant databases from inception to December 2023, using search terms relevant to FND and stigma themes. We employed the method of synthesis by "aggregation and configuration" to synthesise and analyse the data into emergent themes.

RESULTS

We found 127 studies, spanning 148 countries, involving 18,886 participants. Of these, 4889 were patients, 13,123 were healthcare professionals, and 526 were caregivers. Quantitatively, stigma has been mainly studied in patients with functional seizures, and was higher than patients with epilepsy in three studies. Stigma experienced by patients is associated with poorer quality of life and caregiver burden. We found 10 themes and 29 subthemes revealing stigma as a systemic process, with intrapersonal, interpersonal and structural aspects. Few studies examined the perspective of caregivers, the public or online community. We identified six anti-stigma interventions.

CONCLUSION

Stigma in FND is a layered process, and affects patient quality of life and provision of care. Stigma needs to be addressed from the top structures, at governmental level, so that appropriate care pathways can be created, giving patients with FND parity of esteem with other medical conditions.

Psychoeducation interventions for people with non-epileptic seizures: A scoping review

BACKGROUND

Cognitive behavioural therapy (CBT) and other psychological approaches have a growing evidence base for treating Non-Epileptic Seizures (NES). However, communication about the diagnosis can be difficult for clinicians and is not always well received. It is thought that Psychoeducation about NES may improve engagement with treatment such as CBT and may contribute to reductions in the frequency of seizures and improvements in health related quality of life. However, psychoeducational components of treatment are often not evaluated in isolation meaning the specific benefit to patients is not currently well understood.

AIMS

The researchers aimed to examine the outcomes associated with psychoeducational interventions and the content of these programmes for NES.

METHOD

A scoping review was undertaken across four databases with seventeen eligible studies identified which were charted to analyse the data.

RESULTS

Findings revealed that components and modalities of interventions varied as did methods of evaluating the interventions. A number of different outcome measures were used and not all studies reported the significance of findings. Results across studies were inconsistent; however, there was a general trend across the studies of symptom reduction and improvement in mental health.

CONCLUSIONS

Findings illustrate that psychoeducation has potential benefits as an intervention in its own right. However, it may be best placed as a second step in a stepped care model, between initial diagnosis and further psychological treatment. The present literature needs replication and more robust studies for more certain conclusions to be drawn.

Physiotherapy management of functional movement disorders: the patient perspective

PURPOSE

People with functional movement disorders (FMD) are commonly seen in neurology clinics. Despite a recent increase in research, no standardised treatment pathway across the UK exists. Currently only a few qualitative studies in FMD with a focus on psychological aspects and diagnosis have been published. This study aimed to understand people with FMD perceptions of their physiotherapy treatment.

METHOD

Qualitative web-based interviews were conducted with seven participants and an interpretive phenomenological approach was used to identify themes from the data.

RESULTS

Four themes were identified; 1) my brain, mind and body are all me, 2) physiotherapy; what helps and what doesn't, 3) what recovery is to me, and 4) barriers to treatment. Participants desired a combination of psychological and physical approaches, which were holistic, individualised, and delivered by experienced physiotherapists. Limited availability and funding of specialist treatments were barriers to recovery.

CONCLUSION

Holistic management combining psychological and physiological systems seems to be crucial for effective management of FMD. Large variations in physiotherapy treatment exist across the UK. It is hoped that increasing the understanding, amongst healthcare professionals will lead to the development of timely and appropriate pathways for patients that otherwise find themselves lost between medical specialities.IMPLICATIONS FOR REHABILITATIONPatients report more positive experiences when a combined and detailed psychological and physiological explanation to their symptoms is given.An individualised approach working with the patient on activities they find challenging is more preferable than group exercise or impairment based (e.g., strengthening/stretching) treatments.Having a physiotherapist who is experienced in treating functional movement disorders or prepared to learn and understand them helped with adherence to treatment.

Does explaining psychogenic nonepileptic seizures using either a biomedical or biopsychosocial framework affect young people's illness representations? An experimental vignette study

Lay representations of psychogenic nonepileptic seizures (PNES) are important both for understanding public stigma and anticipating patient responses to PNES diagnosis. The current study presents the first evidence of the general public's representations of PNES and the malleability of these understandings to different ways of explaining PNES. An online experimental study exposed participants (n = 193, aged 18-25 years) to a vignette describing a case of PNES in biomedical terms, PNES in biopsychosocial terms, or epilepsy. Subsequent questionnaires assessed participants' illness representations, causal attributions, and stigmatising attitudes regarding the case about which they read. Results suggest that compared with biomedical framings, biopsychosocial explanations increased perceptions of PNES as threatening. While epilepsy was attributed to significantly more biological and less social causes than either of the PNES vignettes, causal attributions did not differ between biomedically- vs. biopsychosocially-framed PNES. Neither were there any differences between the three conditions in stigmatising attitudes towards people who experience seizures. These findings are useful for clinicians delivering a PNES diagnosis and patients disclosing a PNES diagnosis, in helping anticipate responses to these communications. Further research is required to confirm the clinical and societal significance of the study's first insights into the dynamics of lay responses to PNES.

Cultural issues: Perspectives and experiences of patients with dissociative seizures in Argentina

PURPOSE

To explore patients' subjective experience when receiving a diagnosis of Dissociative Seizures (DS) in Buenos Aires, Argentina, and their explanatory models about DS.

METHOD

A qualitative approach using semi-structured interviews was used to gain an in-depth and contextual understanding of the perspectives of 19 patients with DS. Data collection and analysis were followed by an inductive and interpretive approach informed by the principles of thematic analysis.

RESULTS

Four main themes emerged: 1) Reactions to the Diagnosis; 2) Ways of Naming the Disease; 3) Own Explanatory Models; 4) External Explanatory Models.

CONCLUSIONS

This information might help achieve an adequate knowledge of the local characteristics of patients with DS. Most patients could not express any emotions or considerations about being diagnosed with DS, and they related their seizures to a personal or social-emotional conflict and environmental stress; however, family members related patients' seizures to a biological cause. It is important to analyze cultural differences in patients with DS in order to develop appropriate interventions for this specific population.

The clinical management of functional neurological disorder: A scoping review of the literature

OBJECTIVE

To date, there have been no reviews bringing together evidence on the clinical management of functional neurological disorder (FND) and patients', caregivers', and healthcare workers' experiences. This review provides an overview of the literature focused on the clinical management of FND.

METHODS

Four databases were searched, and a consultation exercise was conducted to retrieve relevant records dated from September 2010 to September 2020. Articles documenting diagnostic methods, treatments or interventions, or the experiences and perspectives of patients and healthcare workers in the clinical management of FND were included.

RESULTS

In total, 2756 records were retrieved, with 162 included in this review. The diagnostic methods reported predominantly included positive clinical signs, v-EEG and EEG. Psychological treatments and medication were the most reported treatments. Mixed findings of the effectiveness of CBT were found. Haloperidol, physiotherapy and scripted diagnosis were found to be effective in reducing FND symptoms. Several facilitators and barriers for patients accessing treatment for FND were reported.

CONCLUSION

The literature describing the clinical management for FND has increased considerably in recent times. A wide variety of diagnostic tools and treatments and interventions were found, with more focus being placed on tests that confirm a diagnosis than 'rule-out' tests. The main treatment type found in this review was medication. This review revealed that there is a lack of high-quality evidence and reflects the need for official clinical guidelines for FND, providing healthcare workers and patients the support needed to navigate the process to diagnose and manage FND.

Improved understanding of non-epileptic seizures and reduced emergency health care usage following a single psychoeducational group for children and their parents

RATIONALE

The aim of this study was to evaluate the effectiveness of a three-hour psychoeducation group in improving understanding of non-epileptic seizures (NES), health outcomes and quality of life in young people with NES.

BACKGROUND

Multi-session psychoeducational groups for adults with NES have reported improved psychosocial functioning and reduced NES compared to those who do not receive psychoeducational interventions. To date there have been no studies in young people examining the effects of a single session of psychoeducation.

METHOD

15 young people with NES and their families attended a psychoeducation group within a specialist hospital following a multidisciplinary assessment. The group's effectiveness was evaluated in terms of perceptions of seizure controllability, seizure severity, the management of the condition and health-related quality of life measures.

RESULTS

A significant decrease in accident and emergency (A&E) visits and ambulance call outs was observed following the psychoeducation group. Young people additionally reported increased knowledge of NES and ability to cope with the condition which was maintained at 6-week follow-up. Significant reduction in NES occurrence or quality of life was not observed.

CONCLUSION

Significant reduction in A&E attendance and ambulance use was found following group psychoeducation and improvements in psychosocial functioning and knowledge about NES. Group psychoeducation has the potential to increase child and parental understanding of NES and reduce inappropriate healthcare usage.

Functional seizures: The patient’s perspective of a diagnostic and treatment odyssey

•

Functional seizures remains a complex neuropsychiatric condition to identify and treat.

•

Practitioners must address management of physical symptoms and underlying causes.

•

Management strategies can fail if their reasoning is not properly communicated.

•

Better outcomes may result where treatment rationale is emphasized from outset.

Functional seizures can be challenging to properly diagnose, often leading to delays in treatment. The etiology of functional seizures is multifactorial, with psychological factors identified in many, but not all cases. Misdiagnosis may occur due to clinical features mimicking other medical conditions. Once a correct diagnosis is reached, delivery of definitive, evidence-based treatment may be challenging due to limited availability of specialized resources. Research shows psychological education and cognitive behavioral therapy (CBT) have the greatest efficacy. However, individual differences, including acceptance of the diagnosis, therapeutic alliance, duration of symptoms, comorbidities, and access to care may influence outcomes. There is a critical need for reports that can help identify barriers to effective diagnosis and treatment. We present the diagnosis and treatment of a woman who visited the emergency room after an attack of predominant left-sided paralysis, speech dysfunction and altered awareness. Following multiple daily episodes and visits to multiple medical practitioners, testing led to a diagnosis of functional seizures. While the patient was recommended to undergo a variety of therapeutic interventions, including CBT, she ultimately terminated treatment. In a subsequent interview, the patient revealed her personal experience with perceived limitations of acute management strategies. We explore the complexities of diagnosing and treating individuals with functional seizures.

The experience of trial participation, treatment approaches and perceptions of change among participants with dissociative seizures within the CODES randomized controlled trial: A qualitative study

BACKGROUND

Nested within a large, multicenter randomized controlled trial (RCT) for people with dissociative seizures (DS), the study used purposive sampling to explore participants' experience of participating in an RCT, their experience of DS-specific cognitive behavioral therapy (CBT) and another component of the RCT, Standardized Medical Care (SMC) and their perceptions of and reflections on seizure management and change.

METHODS

A qualitative study using semistructured interviews was conducted with 30 participants in an RCT (the COgnitive behavioral therapy vs standardized medical care for adults with Dissociative non-Epileptic Seizures (CODES) Trial) investigating the effectiveness of two treatments for DS. Key themes and subthemes were identified using thematic framework analysis (TFA).

RESULTS

Analysis yielded three overarching themes: taking part in a treatment trial - "the only thing out there", the experience of treatment techniques that were perceived to help with seizure management, and reflections on an "unpredictable recovery".

CONCLUSIONS

People with DS are amenable to participating in a psychotherapy RCT and described a largely positive experience. They also described the applicability of aspects of DS-specific CBT and SMC in the management of their DS, received within the confines of the CODES trial. Factors that appeared to account for the variability in response to treatment delivery included individual preferences for the nature of sessions, the nature of therapeutic relationships, readiness to discuss trauma, other aspects of emotional avoidance, and whether therapy provided something new.

An investigation into the preferred terminology for functional seizures

There is considerable debate in the literature regarding what to call functional seizures, with terms such as pseudoseizures, nonepileptic attack disorder (NEAD), and dissociative seizures being used. Provision of an accurate diagnosis and coherent explanation is a vital first step in the management of functional seizures and can result in cessation or reduced frequency for some individuals. This study investigated preferences for and offensiveness of terms used to describe functional seizures, and expectations for recovery with psychological treatment. A sample of 87 healthy adults completed an online survey, in which eight different diagnostic terms were ranked in order of preference (1 - most preferred, 8 - least preferred): functional nonepileptic attacks (FNEA), dissociative seizures, functional seizures, psychogenic seizures, NEAD, pseudoseizures, conversion disorder, and hysteria. Replicating Stone and colleagues protocol, each term was investigated for five connotations. Offense scores were calculated from the number of participants who selected 'yes' to at least one of the negative connotations ('Putting it on', 'Mad', and 'Imagining Symptoms'). Expectations about the possibility of recovering through medical or psychological treatment were also recorded. Functional nonepileptic attack was ranked the highest preferred term with dissociative seizures and functional seizures closely following. Nonepileptic attack disorder was the least offensive term, with FNEA and functional seizures joint second. Unsurprisingly, the three least preferred terms were also the most offensive: pseudoseizures, conversion disorder, and hysteria. Expectations of nonrecovery from psychological treatment were lowest for terms implicating a psychological cause: pseudoseizures, dissociative seizures, psychogenic seizures, and hysteria. The results suggest that either the terms FNEA or functional seizures should be adopted by healthcare professionals and patients, as they are the most preferred, least offensive, and expectations for nonrecovery with psychological treatment were moderate compared with the other terms. Limitations and areas for future research are discussed.

Psychogenic non-epileptic seizures: aetiology, diagnosis and management

Psychogenic non-epileptic seizures (PNES) have a significant impact on most patients in terms of distress, disability, loss of income and iatrogenic harm. Three-quarters of patients with PNES are initially misdiagnosed and treated for epilepsy. Misdiagnosis exposes patients to multiple iatrogenic harms and prevents them from accessing psychological treatment. In most cases, the patient's history (and witness accounts) should alert clinicians to the likely diagnosis of PNES. Since this diagnosis may be resisted by patients and may involve ‘un-diagnosing’ epilepsy, video-electroencephalogram recording of typical seizures is often helpful. The underlying causes of PNES are diverse: a model combining predisposing, precipitating and perpetuating factors is a useful way of conceptualising their aetiology. The initial step of treatment should be to limit iatrogenic harm. There is some evidence for the effectiveness of psychotherapy.

Postdiagnosis neurological care for patients with psychogenic nonepileptic spells (PNES)

OBJECTIVE

This study investigated continuity of neurological care for patients discharged from the epilepsy monitoring unit (EMU) with a diagnosis of psychogenic nonepileptic spells (PNES). Because PNES are seizure-like episodes that cannot be explained by abnormal electrical brain activity, they are challenging for patients to understand and accept. Consequently, after diagnosis, patients commonly fail to start recommended psychotherapy and instead pursue redundant medical care. As consistent relationships with healthcare providers may help, we instituted standard follow-up for patients diagnosed with PNES.

METHODS

We performed a retrospective observational cohort study of adults diagnosed with PNES in our EMU. In November 2013, we began routine scheduling of postdischarge follow-up neurology appointments. We compared preintervention (November 2010-October 2013) and postintervention (November 2013-May 2016) cohorts with regard to clinic attendance, understanding the diagnosis, compliance with recommendations, and event frequency.

RESULTS

We identified 55 patients in the preintervention cohort and 123 patients in the postintervention cohort. We successfully implemented the intended practice changes; more patients had follow-up scheduled by discharge (preintervention 2% vs. postintervention 36%, p<0.001), time to follow-up decreased (46days vs. 29, p=0.001), and providers more consistently queried understanding of diagnosis (38% vs. 67%, p=0.03). Explicit planning for continued care did not produce the anticipated patient-provider relationships, as follow-up in clinic was low (38% vs. 37%). For patients who attended clinic, the intervention did not improve establishment of psychiatric care, compliance with medication recommendations, understanding of diagnosis, or event frequency. The odds of reduced event frequency were nonsignificantly increased with understanding the diagnosis (OR 3.75, p=0.14). Recommending antiepileptic drug (AED) discontinuation was associated with increased odds of event freedom (OR 6.91, p<0.01).

SIGNIFICANCE

Scheduling follow-up for patients diagnosed with PNES did not facilitate ongoing patient-provider relationships due to poor clinic attendance. As follow-up is unreliable, the inpatient visit is a critical window of opportunity for intervention.

Emotion and dissociative seizures: A phenomenological analysis of patients' perspectives

Quantitative research has indicated that patients with dissociative seizures (DS) show altered responses to emotional stimuli, in addition to considerable emotional distress and dysregulation. The present study sought to further explore emotional processes in this population, to extend previous findings, and to provide a phenomenological insight into patients' perspectives on these issues. Semistructured interviews were carried out with 15 patients with DS, and the principles of interpretative phenomenological analysis (IPA) were adopted in data analysis. Key themes elicited included: i) general emotional functioning; ii) adverse (stressful/traumatic) life experiences; iii) the role of emotions in DS; iv) relating to others; and v) resilience, protective factors, and coping mechanisms. The clinical and theoretical implications of the findings are discussed.

Explanation as treatment for functional neurologic disorders

There is widespread agreement that the way health professionals communicate the diagnosis of functional neurologic disorders (FND) has a central role in treatment, as it does arguably for most conditions. In this chapter we discuss barriers to effective diagnosis, different models of explanation and evidence regarding the importance of effective communication of the diagnosis in FND, especially movement disorders, and dissociative (nonepileptic) seizures. Debates and disagreements about how to go about this task often reflect different theoretic models held by health professionals rather than evidence. More evidence is required to know whether an initial emphasis on one model is more or less effective than another (e.g., a functional model vs. a psychologic model). We conclude, however, that there are a number of generic components to effective explanation shared by most authors on the topic that form the basis of a consensus. These include taking the patient seriously, giving the problem a diagnostic label, explaining the rationale for the diagnosis, some discussion of how the symptoms arise, emphasis on the potential for reversibility (rather than damage), and effective triage and referral for other treatment where appropriate. Although explanation can sometimes be therapeutic on its own, its role is probably more important as a facilitator to other therapy, including self-help, physical treatments, and psychotherapy.

Providers' perspectives on treating psychogenic nonepileptic seizures: frustration and hope

Recent diagnostic and treatment advances in psychogenic nonepileptic seizures (PNES) have the potential to improve care for patients, but little is known about the current state of PNES care delivery in the Veterans Health Administration (VA). We conducted semistructured interviews with 74 health-care clinicians and workers in the VA, eliciting provider perceptions of PNES care. Data were analyzed according to principles of Grounded Theory. The results revealed variation in care and two emergent domain themes of frustration and hope. Frustration was manifest in subthemes including Complexity, Patient Acceptance, Uncertainty About Treatment, Need for Evidence-based Treatment, and Failure of Cross-Disciplinary Collaboration between neurologists and mental health providers. Hope encompassed subthemes of Positive Attitudes, Developing Cross-Disciplinary Treatment, and Specific PNES Care. Increased resources for diagnosing, treating, and researching PNES have improved awareness of the disorder. More research is needed to understand patients' and caregivers' perceptions of PNES care.

Understanding the perceived treatment needs of patients with psychogenic nonepileptic seizures

Psychological therapy is generally considered the treatment of choice for psychogenic nonepileptic seizures (PNES), but there is a paucity of research on patients' attitudes towards psychological referral. We conducted semistructured interviews with twelve patients with PNES awaiting psychological treatment in order to understand their perceived treatment needs. Data were analyzed inductively according to the principles of thematic analysis. The results indicated that our patients had clear ideas about their treatment needs and a desire to recover by 'returning to normality'. Many participants felt 'caught in limbo' following their PNES diagnosis, however, because of uncertainties about their condition and a lack of support from professionals. This linked with participants feeling unsure whether psychological treatment would meet their needs; there was also apprehension for some participants about the potential negative consequences of therapy. The clinical implications of these findings are discussed, and recommendations for future research are made.

Simultaneous nonepileptic spells and nonorganic hearing loss: A case of comorbid psychogenic symptoms

A twenty-eight-year-old woman with an eight-year history of partial hearing loss presented with a two-year history of worsening deafness and new-onset seizures. Evaluations of tympanic membranes, cochlea, and auditory brain stem reflexes demonstrated no physiologic basis for deafness. Video-EEG monitoring demonstrated that the patient responded normally to spontaneous auditory stimuli and that typical spells were nonepileptic in origin. Although pseudohypacusis is reported in audiology literature, and psychogenic nonepileptic spells are well-studied phenomena in neurology literature, the present case is an unusual case of dual psychogenic symptoms, a relationship that indicates poorer prognosis.

Dissociative seizures--a critical review and perspective

Dissociative seizures are commonly recognized as both a challenging and a poorly understood condition. Though research and publication activity is high, advances in knowledge and insight seem only moderate in recent years. This review focuses on some relevant problematic issues, which might account for a still unsatisfactory research state. A general tendency to deal with dissociative seizures as an assumed disorder in its own nosological right and not as a sole symptom of an underlying psychiatric disorder is most likely one of the major roots of the problem. Unfavorable impacts of this confusion pertaining to clinical management, therapy, and outcome of dissociative seizures are discussed. An alternative point of view, based on the immanent psychiatric and psychodynamic roots of dissociative seizures, is considered.

A feasibility study of a brief psycho-educational intervention for psychogenic nonepileptic seizures

PURPOSE

We have previously reported that one in six patients stops experiencing psychogenic nonepileptic seizures (PNES) following our communication protocol. This prospective multicentre study describes a psycho-educational intervention for PNES building on the initial communication of the diagnosis and examines the feasibility of its delivery by healthcare professionals with minimal experience in psychological therapies.

METHOD

Three healthcare professionals with minimal training in psychological therapies took part in a one-day training course. 20 participants attended for a four-session manualised psycho-educational intervention delivered at three different clinical neuroscience centres. Participants completed self-report measures prior to the intervention at baseline (n=29) and seven months after diagnosis (n=13) measures included seizure frequency, health related quality of life, healthcare utilisation, activity levels, symptom attributions and levels of functioning. Therapy sessions were audiorecorded and manual adherence assessed.

RESULTS

Of 29 patients enrolled into the study, 20 started and 13 completed the intervention and provided follow-up information. At follow-up, 4/13 of patients had achieved complete seizure control and a further 3/13 reported a greater than 50% improvement in seizure frequency. After training, epilepsy nurses and assistant psychologists demonstrated sufficient adherence to the manualised psycho-educational intervention in 80% of sessions.

CONCLUSION

The delivery of our brief manualised psycho-educational intervention for PNES by health professionals with minimal training in psychological treatment was feasible. The intervention was associated with higher rates of PNES cessation than those observed in our previous studies describing the short-term outcome of the communication of the diagnosis alone. An RCT of the intervention is justified but a significant proportion of drop-outs will have to be anticipated.

Common imitators of epilepsy

Many episodic phenomena involving motor, sensory, autonomic, and behavioral functions may imitate epilepsy. The aim of this article is to focus on the various manifestations and the diagnostic and therapeutic challenges of the most common of these disorders, as well as their relationship to emotional aspects. Syncope is caused by reduced global cerebral perfusion. Convulsive movements are sometimes released from subcortical structures, but do not follow the characteristic sequence of tonic-clonic seizures, and postictal symptoms are minimal. Hyperventilation attacks are caused by the metabolic consequences of hypocapnia. Altered blood pH and cerebral vasoconstriction may cause a range of peripheral and central nervous system symptoms. Psychogenic non-epileptic seizures (PNES) are attacks of reduced self-control associated with various behavioral phenomena, usually beyond voluntary control. A detailed clinical history is the most important tool in the differential diagnosis. Various emotional factors may act as immediate triggers in reflex syncope and hyperventilation attacks, whereas in PNES, emotional traumas may be remote and suppressed. Patient education with appropriate explanation of the underlying mechanisms is a fundamental part of the management of these disorders.
